▼ With the increasingly stringent regulations and laws being put in place worldwide with regards to a cleaner and a safer environment, the modern diesel engine has scope to be improved upon to help meet these new standards set for the betterment of our cities. There are many current modes of alternative transport, with diesel-hydrogen combustion being a transitional solution from fossil fuels to hydrogen powered vehicles. The main objective of this research effort was to investigate the effects of intake air enrichment with hydrogen on the performance, combustion, and emissions of a diesel engine. The secondary aim was to design and optimise accurate engine models which can replicate real world experiments and conditions. This becomes increasingly useful in the modern era of engine testing and development as it allows for more manufacturers to test and optimise new combustion methods, without the need for a physical engine, to meet the ever-tightening emissions legislations. Therefore, the accuracy of the models produced could pave the way for more simulations to be carried out via manufacturers with more confidence. The experimental tests were carried out on a 2.0 litre Ford High Speed Direct Injection (HSDI) diesel engine. the engine was tested at various conditions mimicking light- and medium-duty diesel engines. Hydrogen was used via a bottle with the composition of the gas replicating exhaust gas reformed intake air. The percentage of the hydrogen and the start of injection for diesel were altered for the tests. The simulations were carried out on a replicated four-cylinder 2.0 litre Ford HSDI diesel engine on Ricardo Wave® and a single-cylinder DI diesel engine modelled based on a small Yanmar L70N diesel engine. The experimental operating parameters were used in the simulations to measure the level of accuracy achieved with the models on the software. The experimental results showed that with hydrogen enrichment of the intake air, the CO and smoke emissions were reduced significantly, however NOx emissions were found to have increased at certain conditions. The simulations for the multi-cylinder diesel engine showed great promise with an average of 95% accuracy across the operating conditions and emissions measured. The single-cylinder diesel engine displayed low levels of Total Hydrocarbons (THC), Carbon Monoxide (CO), with a slight increase in Oxides of Nitrogen (NOx) emissions but did show high levels of accuracy against literature and other experimental work based on similar operating conditions. Although there is an abundance of literature currently investigating the effects of hydrogen enrichment of the intake air, the new contributions to knowledge of this research is the comparison between simulated and experimental work of transitional combustion methods such as this. This research is believed to help aid the industry in testing and optimising of simulated engine models for a more reliable manufacturing process.

▼ United States natural gas dry production increased by 47% between 2005 and 2015 due to the widespread use of horizontal drilling and hydraulic fracturing to extract gas from shale and other tight formations. Natural gas production and consumption is projected to continue to increase for the foreseeable future. In 2016, the natural gas supply chain delivered 29% of the energy used in the U.S., and natural gas surpassed coal as the leading electricity generating source for the first time in U.S. history. When combusted, natural gas produces less CO2 per unit energy released compared to coal or petroleum. However, uncombusted methane (the primary component of natural gas) has a global warming potential 30 times higher than CO2 on a 100 year time horizon (including oxidation to CO2, but excluding climate-carbon feedbacks). Therefore, the net greenhouse gas impacts resulting from displacement of coal and petroleum by natural gas depend on the emission rate of uncombusted natural gas. Short term climate benefits resulting from coal substitution, for example, are lost if the net rate of methane (CH4) emission from the natural gas supply chain exceeds 3—4% . Three studies were conducted to quantify CH4 emissions from the natural gas industry. In particular, these studies focused on quantifying emissions from the gathering and processing sector and reconciling emissions estimates developed using top-down (tracer flux and aircraft) vs. bottom-up (on-site component-level) measurement approaches. In the first study, facility-level CH4 emissions measurements were made at 114 natural gas gathering facilities and 16 processing plants in 13 U.S. states during a 20-week field campaign conducted from October 2013 through April 2014. Measurement results were combined with facility counts obtained from state air permit databases and national inventories in a Monte Carlo simulation to estimate CH4 emissions from U.S. natural gas gathering and processing operations. Annual CH4 emissions from normal operations at gathering facilities totaled 1699 Gg (95% CI=1539—1863 Gg), while normal operations at processing plants totaled 505 Gg (95% CI=459—548 Gg). CH4 emissions from abnormal operations at gathering facilities were estimated in a separate Monte Carlo simulation based on field observations and a sub-set of field measurements. These emissions totaled 169 Gg (+426%/-96%). In the second study, coordinated dual-tracer, aircraft-based, and direct component-level measurements were made at midstream natural gas gathering and boosting stations in the Fayetteville shale in Arkansas, USA. On-site component-level measurements were combined with engineering estimates to generate comprehensive facility-level CH4 emission rate estimates ("study on-site estimates (SOE)") comparable to tracer and aircraft measurements. Concurrent measurements at 14 normally-operating facilities showed a strong correlation between tracer and SOE, but indicated that tracer measurements estimated lower emissions (regression of tracer to SOE=0.91 (95% CI=0.83—0.99,… Advisors/Committee Members: Marchese, Anthony J.

▼ Increasing concentrations of greenhouse gases in the atmosphere may contribute to global warming. The three most important greenhouse gases are carbon dioxide (mainly from burning fossil fuels and deforestation), methane (mainly from ruminant animals and waste management) and nitrous oxide (mainly from dung, urine, and nitrogenous fertilisers). Dairy farms contribute to greenhouse gas emissions because of nitrous oxide and methane emissions (Whitehead et al., 2009). Herd-homes or stand-off pads are increasingly used on dairy farms to minimise soil pugging and compaction. The manure collected from herd-home bunkers or stand-off pads, may be a source of gaseous emissions (NH₃, N₂O and CH₄). Addition of soil or sawdust to manure prior to land application of manure is a potential best farm management practice to minimise gaseous losses. The specific objectives of the study were to: 1. Determine the optimum flow rate for measurement of ammonia emissions from manure or urea application to soil using a chamber method. 2. Quantify gaseous (NH₃, N₂O and CH₄) emissions from manure or urea after application to soil. 3. Determine the effects of addition of soil or sawdust to manure prior to land application of manure on subsequent gaseous emissions. 4. Determine the effects of surface or incorporated land application of manure or urea on gaseous emissions. A preliminary experiment was undertaken to determine the optimum flow rate to measure ammonia emissions, from manure or urea after application to soil, using a chamber method. The flow rate experiment was set up in the glasshouse with 3 replications of 9 flow rate treatments. A flow rate of 5 L min-¹ (1 exchange volume min-¹) was determined as the optimum air flow rate to use in the chamber method to measure ammonia volatilisation. An experiment was undertaken, with 27 pots and 3 replications of 9 treatments, to investigate the effect of soil or sawdust addition to manure on gaseous emissions (NH₃, N₂O and CH₄), when applied on the land surface or incorporated. The physical and chemical properties of the soil, urine, dung, and sawdust were determined in the laboratory. Addition of sawdust was more effective in reducing ammonia emissions, than addition of soil, to manure prior to land application. The incorporated application of all manure treatments resulted in less NH₃ volatilisation compared to surface application. Total ammonia losses were 51% of the applied N from the surface application and 2% of the applied N from incorporated application of urine and dung with soil, and 15% of the applied N from the surface application and 4% of the applied N from incorporated application of urine and dung with sawdust. Ammonia emissions followed a general pattern of rapid emission on day 2 after the application of the urine and dung to soil followed by a progressive decline over time for both the surface and incorporated application for all the manure treatments applied. Total N₂O loss of 14% of applied N was observed with incorporated application of manure with… Advisors/Committee Members: Luo, Jiafa (advisor), Balks, Megan R (advisor).

▼

Global warming that occurs due to emissions from a country or a country group was studied from two different points of view. Firstly, warming effect caused by Finnish emissions from 1900 to 2100 was assessed using a model that describes removal of greenhouse gases from the atmosphere by pulse response functions, and calculates the radiative forcing caused by an increase in atmospheric concentration. Secondly, Finland's share of global emissions was assessed for the time period during which detailed greenhouse gas inventories were available, i.e. from 1990 to 2003, taking into account uncertainties in emission estimates. The uncertainty estimate was made using literature, measurement data and expert judgement on input parameter uncertainties. Stochastic simulation was used to combine the uncertainties. In addition, uncertainties in different emissions trading schemes were compared at EU level. Greenhouse gases covered by the study were those included in the Kyoto Protocol, i.e. carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), perfluorocarbons (PFCs), hydrofluorocarbons (HFCs) and sulphur hexafluoride (SF6). Sectors covered were energy, industry, transportation, agriculture and waste. LULUCF sectors (land-use, land use change and forestry) were covered more superficially. Finnish greenhouse gas emissions in 2003 were 86 Tg CO2 eq (without LULUCF). According to the results, 95% confidence interval of this figure lies between 82 and 92 Tg CO2 eq. This represents a share of 0.2-0.3% of global emissions. In the same year, Finland's share of global population was 0.1% and share of global GDP 0.4%. The most important contributors to uncertainty were N2O emissions from agricultural soils, N2O from nitric acid production and CH4 from landfills. Inclusion of LULUCF categories in the inventory increased relative uncertainty of net emissions notably (emissions in 2003 were 68 Tg CO2 eq with a 95% confidence interval of 58 to 78 Tg CO2 eq). According to the radiative forcing calculations, forcing caused by Finland will increase from 3 mWm-2 in 1990 to 6-11 mWm-2 by 2100, depending on emission reduction strategies applied, and technological development. In 1990 Finland's share of global radiative forcing was estimated at 0.18% and by 2100 it will decrease to 0.13%, due to increase in global emissions. The results revealed that Finland's share of radiative forcing was smaller than the share of emissions. This was due to Finland's relatively short emission history. It was concluded that uncertainty in EU emissions trading scheme for CO2 (2005-2007) contains rather small uncertainties (±3% based on uncertainties in inventories), but the extension of emissions trading scheme to cover other sectors or gases is likely to increase the uncertainties (up to 21% in Kyoto emissions trading scheme). Both radiative forcing and uncertainty assessment models developed in the thesis can be used in decision making, e.g. for comparing different emission reduction strategies and for planning of future climate commitments.

▼ A well-known issue of tailings is that they have poor consolidation properties, which, in situ, may require several decades or more before the material can be reclaimed. With the accumulation of tailings in the tailings ponds, one unintended consequence of this long-term storage is the evolution of emissions in the ponds. Studies in the last decade have indicated that methane, a greenhouse gas, is produced by methanogen microorganisms in the tailings and that emissions are more readily stimulated by the hydrocarbons in naphtha diluent that is leftover from the bitumen extraction process. More recent studies have also found black, sulfidic zones in the tailings where toxic, hydrogen sulfide gas may be being produced in considerable amounts, but it is unknown how much hydrogen sulfide or other reduced sulfur compound emissions are being released from the ponds or whether these emissions are also stimulated by naphtha diluent. The objectives of this study were as follows: 1) Determine whether there are advantages to further reducing the diluent concentrations in the tailings with respect to methane, carbon dioxide, and reduced sulfur compound emissions; 2) Between methane, carbon dioxide, and reduced sulfur compound emissions, which are the most concerning quantity wise under a worst case, high diluent scenario; and 3) Aside from diluent, are there other chemical factors that play a role in the types of emissions generated from tailings. A mesocosm experiment was conducted using Suncor Energy Inc. Pond 2/3 mature fine tailings, pond water (Pond 2/3 or surrogate pond water), with naphtha diluent amendments of 0% w/v, 0.2% w/v, 0.8% w/v, and 1.5% w/v. Chromatography gas analysis revealed that all greenhouse gases and reduced sulfur compound emissions increased with increasing naphtha diluent concentrations. Therefore, further reducing the concentration of residual diluent in the tailings ponds is anticipated to decrease the amount of greenhouse gases and reduced sulfur compound emissions that are produced in tailings. With respect to the quantities of emissions produced, at a worst-case diluent scenario of 1.5% w/v, methane emissions were the highest, followed by carbon dioxide, and then the combined amount of reduced sulfur compounds. Within the reduced sulfur compounds, amounts emitted from highest to lowest were in the order of hydrogen sulfide and 2-methylthiophene > 2,5-dimethylthiophene > 3-methylthiophene > thiofuran > butyl mercaptan > carbonyl sulfide, with hydrogen sulfide and 2-methylthiophene combined making up 81% of the total reduced sulfur compound emissions. The remaining sulfate concentrations within the tailings samples was also an important factor with regards to the types of emissions produced as there was a system shift from sulfur emissions production to methanogenesis after sulfate became depleted. Lastly, our results indicated that hydrogen sulfide, methane, and carbon dioxide were produced from biological sources associated with the mature fine tailings whereas the remaining reduced…

▼ There is growing evidence that real world, on-road emissions from mobile sources exceed emissions determined during laboratory tests and that the air quality, climate, and human health impacts from mobile sources might be substantially different than initially thought. Hence, there is an immediate need to measure and model these exceedances if we are to better understand and mitigate the environmental impacts of mobile sources. In this work, we used a portable emissions monitoring system (PEMS) and artificial neural networks (ANNs) to measure and model on-road fuel consumption and tailpipe emissions from Tier-2 light-duty gasoline and diesel vehicle. Tests were performed on at least five separate days for each vehicle and each test included a cold start and operation over a hot phase. Routes were deliberately picked to mimic certain features (e.g., distance, time duration) of driving cycles used for emissions certification (e.g., FTP-75). Data were gathered for a total of 49 miles and 145 minutes for the gasoline vehicle and 52 miles and 165 minutes for the diesel vehicle. Fuel consumption and emissions data were calculated at 1 Hz using information gathered from the vehicle using the onboard diagnostics port and the PEMS measurements. Route-integrated tailpipe emissions did not exceed the Tier-2 emissions standard for CO, NOX, and non-methane organic gases (NMOG) for either vehicle but did exceed so for PM for the diesel vehicle. We trained ANN models on part of the data to predict fuel consumption and tailpipe emissions at 1 Hz for both vehicles and evaluated these models against the rest of the data. The ANN models performed best when the training iterations (or epochs) were set to larger than 25 and the number of neurons in the hidden layer was between 7 and 9, although we did not see any specific advantage in increasing the number of hidden layers beyond 1. The trained ANN model predicted the fuel consumption over test routes within 5.5% of the measured value for both gasoline and diesel vehicles. The ANN performance varied significantly with pollutant type for the two vehicles and we were able to develop satisfactory models only for unburned hydrocarbons (HC) and NOX for diesel vehicles. Over independent test routes, the trained ANN models predicted HC within 12.5% of the measured value for the gasoline vehicle and predicted NOX emissions within 3% of the measured values for the diesel vehicle. The ANN performed better than, and hence could be used in lieu of, multivariable regression models such as those used in mobile source emissions models (e.g., EMFAC). In an ‘environmental-routing’ case study performed over three origin-destination pairs, the ANNs were able to successfully pick routes that minimized fuel consumption. Our work demonstrates the use of artificial neural networks to model fuel consumption and tailpipe emissions from light-duty passenger vehicles, with applications ranging from environmental routing to emissions inventory modeling.

Este estudo faz uma análise dos níveis de emissões veiculares relacionados com os problemas de poluição na cidade de São Paulo. Utilizando a metodologia denominada bottom-up, avalia de forma teórica os índices de poluentes que saem pelo tubo de escapamento da maior frota de veículos leves do país. São abordados tópicos relacionados com o dia-a-dia da cidade como crescimento da frota, combustíveis, transporte público, poluição atmosférica e seus efeitos à saúde e ainda a influência atmosférica na região. Foram feitas diversas simulações no decorrer do estudo denominadas de cenários, que são baseadas na simples, porém eficiente, aplicação da metodologia bottom-up que utiliza, para os cálculos, os fatores de emissões de acordo com a evolução das fases do PROCONVE para obter a quantidade de determinados poluentes emitido por ano. Os cenários permitem a substituição dos veículos mais velhos por veículos novos e apresentam resultados positivos para o meio ambiente, dentre eles aqueles que podem ser considerados como alternativas ousadas e outros podem ser vistos como alternativas mais conservadoras, mas todos demostram melhorias significativas para a qualidade do ar na cidade de são Paulo. A evolução das fases citadas trouxeram muitos benefícios ao meio ambiente por meio das novas tecnologias desenvolvidas e embarcadas nos veículos novos e que não deixam de ser a solução para o futuro, onde melhorias nas condições atmosféricas devem ser alcançadas. Questões como políticas públicas e legislações específicas para a substituição dos veículos velhos da rua, não saem da teoria. Na prática o trânsito está cada vez mais caótico, em partes pela quantidade de carros em péssimas condições de uso que ainda circulam e quebram todos os dias, afetando diretamente a qualidade do ar na metrópole paulista.

This study presents an analysis of the levels of vehicles emissions related to the pollution problems in São Paulo City. Using a methodology called bottom-up, this thesis presents a theoretical evaluation on the rates of pollutants coming out the exhaust pipe of the largest light vehicles fleet in Brazil. Issues related to daily city activities such as the fleet growth, fuels, public transportation, air pollution and its effects on the population health and the atmospheric influence in the region as well are presented. Simulations for scenarios drawn were based on a simple but efficient, implementation of bottom-up approach that employs, for calculations, the emission factors according to the changing phases of PROCONVE (the Brazilian National Program for the Pollution Control of Vehicles) for the amount of pollutants emitted per year. The scenarios consider that replacement of older vehicles by new ones is positive for the environment. Some scenarios may be considered as non-conservative alternatives and others can be seen as conservative, but all demonstrate significant improvements to the quality of air in São Paulo City. The evolution of the phases mentioned have brought many benefits to the environment through new…

▼ This research develops an optimization model for eco-driving at signalized intersection. In urban areas, signalized intersections are the ?hot spots? of air emissions and have significant negative environmental and health impacts. Eco-driving is a strategy which aims to reduce exclusive fuel consumption and emissions by modifying or optimizing drivers? behaviors. With the help of vehicle-to-vehicle (V2V) communication and vehicle-to-infrastructure communication (V2I), eco-driving could utilize the signal phase and the queue-discharging time information to optimize the speed trajectories for the vehicles approaching an intersection in order to reduce fuel consumption and emissions. A few research studies have been conducted on the development of algorithms that utilize traffic signal information to reduce fuel consumption and emissions. Hence, the goal of this research is to develop an optimization model to determine the optimal eco-driving trajectory (the speed profile) at a signalized intersection, which aims to achieve the minimization of a linear combination of emissions and travel time. Then enumeration method, simplex optimization and genetic algorithm are investigated to determine a practicable and efficient method to solve the proposed optimization problem. As various scenarios of distance from the vehicle to the intersection, queue discharging time and weights of emission/travel time will lead to different optimal trajectories and different emissions and travel times. A sensitivity study is conducted to analyze and compare the performance of the optimal solution in various scenarios of different such parameters. In addition, a baseline study is conducted to investigate the benefits of eco-driving when drivers only decelerate in advance but not apply the recommended speed trajectory. The results of case study show that genetic algorithm is a preferred method to solve the proposed optimization problem; Eco-driving could achieve satisfied reduction in emissions without significantly increasing travel time and emissions is more sensitive to various scenarios than travel time; Eco-driving still could achieve reduction in emissions as long as the drivers decelerate earlier even though the they would not apply the recommended speed trajectory under certain conditions.

▼ The operation of Kosova’s Thermal Power Plants (TPP) from the time of their construction had the goal of supplying of Kosova with electricity and also sometimes exporting to parts of old Yugoslavia. This contributed significantly in developing the Kosova’s economy but as with all coal-fired power plants it added to the problem of environmental pollution. This project provides great assistance for promoting environmental protection and assesses the best new power plant technologies available. This capstone project assesses the levels of atmospheric emissions (dust, SO2, CO2 and NOx) from the existing TPP’s in Kosova and the projections of future emissions until the existing plants are decommissioned and new power plants becomes operational. Also the project addresses the necessary measures to reduce the pollution and analyze the impact of atmospheric emissions on the environment from the proposed new TPP, which is planned to be constructed in Kosova in the next few years. In order to represent a range of long-term planning option, this capstone project discusses the above from the perspective of four broad scenarios for the period 2010-2030. These four scenarios are: Scenario 1 – the existing TPP (Kosova A and B) with no new generation capacity and without abatement measures; Scenario 2 – the existing TPP with abatement measures (upgrading the electrostatic precipitators - ESP, only for TPP B), construction of the new HPP Zhur 293MW and new TPP Kosova C with capacity 1x500MW; Scenario 3 – the existing TPP with abatement measures (upgrading the electrostatic precipitators - ESP, only for TPP B), construction of the new HPP Zhur 293MW and new TPP Kosova C with capacity 2x500MW; and 7 Scenario 4 – the existing TPP with abatement measures (upgrading the electrostatic precipitators - ESP, only for TPP B), construction of the new HPP Zhur 293MW and new TPP Kosova C with capacity 4x500MW. In all four scenarios it is assumed that TPP Kosova A will be decommissioned by 2017. From the financial analysis of four scenarios presented in the capstone, the deficit or surplus of electricity may cost or benefit a considerable amount of money. The following figure presents the potential earnings from exports (scenario 3 and 4) and potential expenses from the electricity imports (scenario 1 and 2). The total CO2 emissions for all scenarios show that intensive power generation reflects higher emissions. The consequences of extending the limits of CO2 emissions may cost the considerable expenses having in mind that the credits for CO2 in the future will be high.

▼ A controlled hydraulic fracture experiment was performed on two medium sized (11” x 11” x 15”) synthetic layered blocks of low permeability, low porosity Lyons sandstone sandwiched between cement. The purpose of the research was to better understand and characterize the fracture evolution as the fracture tip impinged upon the layer boundaries between the well bonded layers. It is also one of the first documented uses of passive microseismic used in a laboratory environment to characterize hydraulic fracturing. A relatively low viscosity fluid of 1000 centipoise, compared to properly scaled previous work (Casas 2005, and Athavale 2007), was pumped at a constant rate of 10 mL/minute through a steel cased hole landed and isolated in the sandstone layer. Efforts were made to contain the hydraulic fracture within the confines of the rock specimen to retain the created hydraulic fracture geometry. Two identical samples and treatment schedules were created and differed only in the monitoring system used to characterize the microseismic activity during the fracture treatment. The first block had eight embedded P-wave transducers placed in the sandstone layer to record the passive microseismic emissions and localize the location and time of the acoustic event. The second block had six compressional wave transducers and twelve shear wave transducers embedded in the sandstone layer of the block. The intention was to record and process the seismic data using conventional P-wave to S-wave difference timing techniques well known in industry. While this goal ultimately not possible due to the geometry of the receiver placements and the limitations of the Vallene acquisition processing software, the data received and the events localized from the 18 transducer test were of much higher numbers and quality than on the eight transducer test. This experiment proved conclusively that passive seismic emission recording can yield positive results in the laboratory. Just as in the field, this provides one of the best far field (away from the well bore) measurements to assess hydraulic fracture behavior. It also provides a calibration tool to extend laboratory results to field scale endeavors. The identification of strong microseismic activity at stress states far below fracture initiation confirms that rocks are critically stressed meta-stable materials and that microseismicity is caused by stress changes, not fractures directly. Advancements are necessary to fully exploit the potential of the microseismic method in laboratory sized samples. Both processing and visualization enhancements are necessary to realize the full benefits of this promising technology in the laboratory environment.

▼ The need to understand the effect of policy decisions on environmental indicators is strong. The emergence of new technologies brought about by connected vehicle technologies, which are difficult to evaluate in field settings, means that policies must often be evaluated with software models. In these cases, however, the transportation model and the emissions model are often separate, and multiple different ways to connect these models are possible. Although the estimations provided by each model will vary, each method also differs in terms of the computational time. This research is motivated by the need to understand the consequences of choosing a particular method to link a traffic and emissions model. Within the literature, aggregated approaches that simply use average speeds and volumes are often selected for their convenience and lower data needs. A number of different scenarios were therefore constructed to compare the estimates of these aggregated approaches to other methods that use disaggregated data, such as the use of individual discrete trajectories, the use of a velocity binning scheme that characterises networks based on their velocity profile or the use of a clustering algorithm developed for this study. This research presents a clustering algorithm that can be used to reduce the computational loads of an emissions estimation process without loss of accuracy. The results of the analysis highlight the consequences of choosing each approach. Aggregated approaches produce unreliable estimates as they are backed by assumptions that may not be valid in every case. Using individual trajectories creates high computational loads and may not be feasible in all cases. The wealth of data available from a traffic microsimulation mean that using an aggregated approach neglects to utilise the full potential of the model; however, the hybrid approaches presented in this research (clustering and velocity binning) were found to make excellent use of this data while still minimizing computational demands.

▼ The efficiency of an internal combustion engine is highly dependent on the peak pressure at which the engine operates. A new compound engine concept, the double compression expansion engine (DCEE), utilizes a two-stage compression and expansion cycle to reach ultrahigh efficiencies. This engine takes advantage of its high-integrity structure, which is adapted to high pressures, and the peak motored pressure reaches up to 300 bar. However, this makes the use of conventional combustion cycles, such as the Seiliger–Sabathe (mixed) or Otto (isochoric) cycles, not feasible as they involve a further pressure rise due to combustion. This study investigates the concept of isobaric combustion at relatively high peak pressures and compares this concept with traditional diesel combustion cycles in terms of efficiency and emissions. Multiple consecutive injections through a single injector are used for controlling the heat release rate profile to achieve isobaric heat addition. In this study, the intake pressure is varied to enable a comparison between the isobaric cases with different peak pressures, up to 150 bar, and the mixed cycle cases. Tests are performed at several different levels of EGR. The experiments are performed on a 12.8 L displacement 6-cylinder Volvo D13C500 engine utilizing a single cylinder with a standard 17-compression-ratio piston. In this study, the cylinder represents the high-pressure unit of the DCEE. The fuel used in all the experiments is a standard EU diesel. In each target condition, the different injection strategies are compared with the total amount of fuel kept relatively constant. The results prove that the isobaric combustion concept is feasible with a traditional injection system and can achieve gross indicated efficiencies close to or higher than those of a conventional diesel combustion cycle. Moreover, the results show that with an isobaric cycle, heat transfer losses can be reduced by over 20%. However, the exhaust energy is higher, which can eventually be recovered in the second stage of expansion. Thus, this cycle could be suitable for the DCEE concept. The CO, UHC and soot emission levels are proven to be fairly similar to those of the conventional diesel combustion. However, the NOx emissions are significantly lower for the isobaric combustion.

▼ This thesis was done for Nokian Tyres Plc in order to define the greenhouse gas emis-sions of Nokia factory. The study was carried out as a greenhouse gas assessment with “cradle-to-gate” framing by following PAS 2050 guidelines. The work included data collection and emission calculations. In addition to the assessment, the thesis work included creating a tool that could be used for calculating emission on a yearly level. The calculator was done by using Microsoft Excel -software. In 2011, the total greenhouse gas emissions of Nokia factory were 3 582 kilograms of carbon dioxide equivalents per tonne of tyres produced. 81% of the emissions were formed by raw material acquisition, 18% by production process at the factory, from which purchased energy composes 17%, and less than one per cent by offices and work trips. Since most of the emissions are caused by raw material acquisition and are therefore difficult to control, the focus should be put on developing the procedure into more energy efficient. The results of the study cannot be directly compared to other assessments without familiarising oneself with the used methods. The reliability of the comparison is dependent on the chosen standard because there are differences in the defining methods between standards. Some problems were also encountered when determining the emission factors and therefore their accuracy should be taken with reserve. The background data about raw materials is not published in the thesis. Also the calculator and its calculation sheets for partial processes will remain confidential. Thus, appendices 2-5 are not published.; Tämä opinnäytetyö on tehty Nokian Renkaat Oyj:n toimeksiannosta Nokian tehtaan kasvihuonekaasupäästöjen määrittämiseksi. Tutkimus on tehty noudattaen PAS 2050 ohjeistusta, jonka perusteella kasvihuonekaasupäästöselvitys on rajattu koskemaan ”kehdosta portille” -rajaukseen kuuluvia prosesseja. Työ piti sisällään tiedon keräämistä sekä hiilidioksidilaskelmien tekoa. Kasvihuonekaasupäästöselvityksen lisäksi tavoitteena oli luoda laskuri, jolla kasvihuonekaasupäästöt voitaisiin laskea vuosittain. Päästölaskuri tehtiin Microsoft Excel -ohjelmaa käyttäen. Vuonna 2011 Nokian tehtaan kasvihuonekaasupäästöt olivat yhteensä 3 582 kilogrammaa hiilidioksidiekvivalenttia yhtä tuotettua rengastonnia kohden. Kokonaispäästöistä 81 % koostui raaka-aineiden hankinnasta, 18 % tehtaan tuotantoprosesseista, joista jopa 17 % oli ostetun energian aiheuttamia, ja alle yksi prosentti oli toimistoista ja työmatkoista aiheutuneita päästöjä. Raaka-aineiden hankinnasta aiheutuneiden kasvihuonekaasupäästöjen pienentäminen on vaikeaa, koska valtaosa päästöistä on raaka-ainetuottajien omista prosesseista johtuvia. Näin ollen huomio tulisikin keskittää ostetun energian päästöihin energiatehokkuutta parantamalla. Kasvihuonekaasupäästöselvityksen tuloksia ei tulisi suoraan verrata muihin selvityksiin tutustumatta niiden käyttämiin ohjeistuksiin. Koska ohjeistukset eroavat toisistaan joissakin yksityiskohdissa, eri perustein lasketut…

▼ Natural peatlands are important sinks of carbon (C) and vital in the global C cycle. Despite covering just 3% of the earth’s land mass, they store as much C as all terrestrial biomass. Drainage for forestry alters the hydrology and chemical reactions in peatlands, converting them from sinks to sources of carbon dioxide (CO2) and nitrous oxide (N2O), while reducing methane (CH4) emissions. Rewetting is considered an important tool in climate change mitigation and is utilized in addition to other management tools such as Sphagnum introduction to return the C sink function of peatlands and re- establish peat forming conditions in degraded peatlands. The first aim of this study was to investigate the controls on CO2, CH4 and N2O dynamics in two rewetted former peatland forest sites in Ireland; one blanket peatland eight years after rewetting (Pollagoona) and one raised peatland three years after rewetting (Scohaboy), produce annual greenhouse gas (GHG) balances for both peatlands and compare them with natural and forested systems. The second aim was to compare the chemical and physical properties of natural, drained and rewetted peatlands in order to assess the effect of both drainage and subsequent rewetting on peatland properties. Gas fluxes were measured using the chamber method. Micro sites comprising the dominant vegetation at the study site were established and gas balances produced for one year. Although interannual variablility influences GHG emissions from peatlands, results from this study represent fluxes in a year without extreme climatic episodes. In this study, both sites acted as CO2 and CH4 sources. Although Pollagoona was an overall CO2-C source (131.6 g CO2-C m-2 yr-1), one microsite acted as a strong C sink (-142.84 g CO2-C m-2 yr-1). Methane emissions were small, totalling 2.94 ± 1.03 g CH4-C m-2 yr-1. Molinia caerulea plots were both the greatest CO2-C (168.4 g CO2-C m-2 yr-1) and CH4-C (2.53±1.01 g CH4-C m-2 yr-1) sources. Pollagoona experienced N2O uptake (-11.78 μg m-2yr-1) due to the behaviour of one microsite during the study period Scohaboy acted as a large CO2-C (585.3 g CO2-C m-2 yr-1) source in all microsites despite re- vegetation of non- brash plots due to the availability of fresh organic matter across the site. Scohaboy was also a CH4 source emitting 3.25 ± 0.58 g CH4-C m-2 yr-1. Both CO2-C (819.31 g CO2-C m-2 yr-1) and CH4-C (4.76 ±0.98 g CH4-C m-2 yr-1) emissions were highest from the brash plots. Annual nitrous oxide losses were small over the study period (72 μg m-2yr-1). Pollagoona displays little variability in elemental composition between land use type, while significant differences were observed in C and N content between land uses in Scohaboy. Unexpectedly N content of the peat did not increase with depth in four of the six peat cores analysed and this is reflected in their C:N ratio. All cores contained both labile and recalcitrant OM. Refractory OM was found in forestry samples from both sites and Scohaboy natural. Comparisons between land use types indicate that drainage and… Advisors/Committee Members: Byrne, Kenneth A., EPA.
